Description
Technical field
The present invention relates to the technical field of agriculture chemical compounding, is using chlorine Fampridine acid and mesotrione as active ingredient, is used for
Prevent and kill off corn field, sugarcane field annual grassy weeds, the herbicidal composition of specially a kind of chlorine Fampridine acid and mesotrione and should
With.
Background technology
Chlorine Fampridine acid (aminopyralid), chemical name：4- amino -3,6- dichloropyridine -2- carboxylic acids, chlorine Fampridine
Acid is a kind of pyridines herbicide, is widely used in the control of weeds of mountain region, grassland, lawn, plantation and bare place.It can prevent and treat
Annual or perennial broadleaf weed.Structural formula is as follows：
Mesotrione (mesotrione) chemical name：2- (2- nitro -4- mesyl benzene adds acyl) hexamethylene -1,3- two
Ketone.Mesotrione suppresses the activity of p-hydroxypyruvate dioxygenase (HPPD), and amino acid Lip river propylhomoserin can be converted into matter by HPPD
Body quinone.Plastoquinone is the confactor of phytoene desaturase.It is the key enzyme of herxheimer-liked reaction.Use
There is yellow symptom and cause withered spot therewith in 3-5 days implants separate living tissues of mesotrione, throughout whole plant after fortnight.Have
Faintly acid, in inoic acid soil, tightly can adsorb on organic substance, in neutral or basic soil, be not easy by
The anionic form of absorption is present.It is a kind of new three ketones herbicide, both can be with before seedling soil list processing, can also be in after seedling
Cauline leaf spraying is carried out, quick while, mesotrione residual life in soil is short, to succession crop safety.Meanwhile it is given birth to
Thing activity exceedes more than 10 times of sulphur humulone, with more potentiality to be exploited and competitiveness.Structural formula is as follows：
